Scroll page to top/bottom bookmark

[fstjohn]

Here's a handy little javascript I found somewhere on the internet. It works in Firefox, Chrome/chromium, Brave and derivatives. Just create a new bookmark and paste the javscript into the URL field. Copy and paste the up/down arrow into the bookmark name field. Click on the bookmark to move to the top or bottom of the page. This replaces any of the several extensions that do basically the same thing.

javascript:(function () {var paBody = document.body, paHtml = document.documentElement, paMaxY = Math.max(paBody.scrollHeight, paBody.offsetHeight, paHtml.clientHeight, paHtml.scrollHeight, paHtml.offsetHeight) - window.innerHeight, paBreakPoint = 300; if(window.scrollY > paBreakPoint || paBreakPoint >= paMaxY && window.scrollY != 0) window.scroll({top: 0, behavior: 'smooth'}); else window.scroll({top: paMaxY, behavior: 'smooth'});})();
